Acid3 Test results of Firefox, Chrome, Opera and Epiphany browsers

I just thought of comparing browsers I have installed in my Ubuntu 10.04 laptop. Here is the Acid test results for all four major browsers Firefox, Chrome, Opera and Epiphany. Firefox is powered by Gecko engine, Chrome and Epiphany powered by WebKit engine and Opera by Presto. Here is an introduction for Acid test in Wiki:

Acid3 is a test page from the Web Standards Project that checks how well a web browser follows certain selected elements from web standards, especially relating to the Document Object Model (DOM) and JavaScript.

Firefox version: 4.0b1 Score: 97/100

Google Chrome version: 5.0.375.99 Score: 100/100

Opera version: ﻿10.60 internal Score: 100/100

Epiphany version: 2.30.2 Score: 100/100

I wonder why Firefox is still struggling to pass Acid3 test with 100% score? Does it mean that Gecko engine behind Firefox is lagging behind the WebKit and Presto? Can some one throw light on this? What about your comment on Eric Meyer’s criticism on latest Acid3 test?

Interface desing is very interesting as for me. I’ve been using Mozilla for some years and it’s the most stable browser from all I’ve ever used (Opera, IE)
